Description

If I use Stable Diffusion to generate textures the generated image will very often have multiple white stripes (with / without tiling enabled).

Txt2img

Example:

![Image](https://github.com/user-attachments/assets/84626a45-9c5d-4310-a1b1-12520879b2e5)

Even if I change text of the negative or positive prompt it is often impossible to generate seamless textures without any stripes.
Is that a bug or how can I generate textures without stripes?

Research direction

No source file, test, model, sampler, or generation settings are identified. Start by reproducing the reported stripes from the attached example with the same Stable Diffusion texture-generation conditions, then determine whether the behavior is model-specific or reproducible in the application. Done means establishing a clear cause and a validated fix or documented generation guidance.
